Description

Fixed block is installed to connection part on the external surface of structural member
The present invention relates to fixed block is installed to connection part on the deformable material external surface of structural member.
Usually need on plastic member such as plastic casing, provide fixing device, so that other element can be installed on the described member.Therefore, known each opening that harder plastic whorl inserting member can be pressed into member is for example by hot melt operation, ultrasonic welding etc.But, this method can not be used for thin-walled member, for example the housing of mobile phone (cell phone).A kind of feasible method is to make this member that all-in-one-piece screw thread bump be arranged by injection moulding.But, this can only be used for the very simple member of geometrical shape.
An object of the present invention is to provide the connection part on the external surface of structural member that a kind of fixed block improved, that be used for the material that intensity is higher relatively is installed to the relatively low material of intensity.
Another purpose of the present invention provides a kind of connection part that fixed block is connected with member, and this connection part can be installed to fixed block on the member of separately making in very simple mode, and any hole or opening need not arranged on this component wall.
In connection part of the present invention, fixed block comprise main body with functor and with described main body all-in-one-piece flange connector, member has at least one connection bump, and this connection bump is integral with external surface of structural member and matches with respective notches on the flange connector of fixed block.This connection bump has the turnover crimp at its free end, and this turnover crimp forms by the material deformation of connection bump, and it guarantees connection bump is remained on the flange connector.
So really guarantee to be connected with very high resistance to torsion, pull resistance and anti-shearing stress face-to-face between fixed block and the member.Because it need not punch or opening on the wall of member, the wall of member can be done quite thinly.
Member is preferably made by thermoplastic material, but also can be made by light metal.Under any circumstance, member all must be made by flexible material, so that form the turnover crimp at the end of connection bump.
When member was made by thermoplastic material, the turnover crimp can be separated operation by common hot melt and form, and for example separated operation by ultrasonic welding, straight line or spin friction weldering or other hot melt.But, when member was made by light metal, the turnover crimp preferably formed by cold deformation (for example riveting operation).
For the ease of understanding the present invention, accompanying drawing has been represented the preferred embodiments of the present invention, by this embodiment and get in touch following explanation, can understand structure of the present invention and its many advantages at an easy rate.
Fig. 1 is the fixed block before attended operation and the perspective view of member;
Fig. 2 is illustrated in the view that is similar to Fig. 1 in the intermediate steps process of attended operation;
Fig. 3 is illustrated in the view that is similar to Fig. 1 and Fig. 2 after attended operation is finished.
Fixed block 2 shown in Figure 1 will be installed on the flat outer surface 6 of member 4.This member 4 is thin-wall parts, for example the housing of mobile phone (cell phone).
Member 4 is made by the relative materials with smaller of intensity, for example thermoplastic material or light metal.Fixed block 2 is made by the bigger material of intensity, particularly metal or harder plastics.Therefore, when fixed block 2 was rigidly connected on the member 4 with being integral, this fixed block 2 can be realized the fixed function of member 4.
In the illustrated embodiment, fixed block 2 comprises main body 8 and flange connector 10, and this flange connector 10 is integral with main body 8 and three recesses 12,14 are arranged.The outer surface 6 of member 4 has all-in-one- piece projection 16 and 18, and this projection 16 and 18 shape match with recess 12,14 respectively.
Flange connector 10 is the annular flange flange that approach, and it is shaped as circle in the illustrated embodiment; But it also can be other shape.As shown in the figure, being shaped as of recess 12 passed flange connector 10 and the annular wall section of extending, and recess 14 to be basic on flange connector 10 outer peripherys be the groove of semi-circular cross-section.Projection 16 on member 4 outer surfaces 6 and 18 sectional shape and relative position adapt with recess 12 and 14 respectively, and promptly projection 16 is shaped as the annular wall section, and projection 18 is a cylindricality.
Projection 16 length is greater than the thickness of flange connector 10, and like this, when fixed block 2 located and cooperates with projection 16 and 18, projection 16 was extended a prearranging quatity (see figure 2) above the upper surface of flange connector 10.The free end of projection 16 will turn down crimp 20 (see figure 3)s thereby produce by the turnover distortion, and this turnover crimp 20 guarantees fixed block 2 is remained on the member 4, and this will be described in detail below.
Column-shaped projection 18 is not the sin qua non's, can omit, and the thickness of the length of this column-shaped projection 18 and flange connector 20 is suitable, so it can not have the turnover crimp above the upper surface of flange connector 20.The function of this column-shaped projection is anti-the relatively rotating property that increases this connection part.
Should also be appreciated that number, shape and the position of recess 12,14 and projection 16,18 can be chosen to be different from illustrated embodiment.The ring segment shape of recess 12 and projection 16 can provide very large shear resistant in the space of minimum.Also can take other appropriate geometry according to special-purpose.As shown in the figure, the wall of recess 12 and projection 16 are extended perpendicular to the outer surface 6 of member 4.But, also can make recess 12 that little tapering is arranged, so that projection is inserted in the fixed block 2.Also can select to make recess 12 along the opposite direction convergent, like this, the exceptional space that holds material be arranged when material deformation forms turnover crimp 20.This will increase the pull resistance of connection part.Preferably, the size of projection 16 is slightly less than recess 12, so that projection 16 is inserted in the fixed block 2.
Certainly, omissible protruding 18 also can have the shape different with shape shown.For example, it can be that the shape angle, flank profil shape or that tooth is arranged is arranged.And projection 18 also can be similar with projection 16, and its axial length enough provides turnover crimp 20, thereby also help the axial restraint of fixed block 2.
Become the main body 8 of the fixed block 2 of hollow cylinder that functor 22 is arranged in the illustrated embodiment.In the illustrated embodiment, this functor 22 comprises a smooth hole; Perhaps, this functor 22 can comprise tapped hole, a part of hasp (closure) or retaining member, smooth or threaded bolt or similar fastener.
As shown in the figure, can there be rib or fluted the bottom surface of flange connector 10, so that increase the anti-relative revolving ability between fixed block 2 and the member 4.
The connection part that comprises fixed block 2 and member 4 can be with following method manufacturing:
At first make fixed block 2 and member 4, for example by injection moulding or other appropriate method with being separated from each other.
Then fixed block 2 is located on the outer surface 6 of member 4, like this, projection 16 and 18 is respectively charged in recess 12 and 14, as shown in Figure 2.The size of each parts can be selected like this, and for example, projection 16 is packed in the recess 12 with a gap, and projection 18 is packed in the recess 14 by press fit.Fixed block 2 is accurately located with respect to member 4.
Then by making material plasticizing and distortion with soldering appliance 24 (Fig. 2 schematically illustrates), be similar to riveted joint or crimping (grimping) operation-connect really so that make between fixed block 2 and the member 4 thereby make the free end that stretches out of projection 16 be deformed into turnover crimp 20-.The size and dimension of turnover crimp 20 can be selected according to special-purpose.
